: Well, if you do
: int main(void) { printf("Hello world\n"); }
:
: and compile with gcc -Wall, gcc will complain about reaching the end of a
: non-void function. Declaring main() to be void will remove that warning.
: I use void main(void){...} a lot.
A simple return 0; at the end would fix the problem. Otherwise your
program has a bug in that it will return a random value to the shell
for its exit status (generally 11).
